For a while I've been noticing significant degradation of the backlight on my dilapidated iBook G4. So, yesterday, my dad and I spent a few hours replacing the CCFL backlight bulb.
Hitachi GST (no longer) Sucks
UPDATE January 2007: I got the replacement drive, and it has been working fine for a few months now. Hitachi's service was quick and painless, and while I'm still not 100% sure about the quality of Travelstar drives (since I've had them fail since the IBM days), I'm satisfied that the problem's fixed.
